Gerard Butler plays a scientist (this movie is already hilarious) who has invented a complex satellite system surrounding our planet that controls the weather and prevents the devastating events that have resulted from climate change. The system begins to malfunction a few years after he has been fired from the program and it has been taken over by his brother (Jim Sturgess, who after more than a decade in the business still can’t figure out what to do with his hair), so Butler is sent up into the international space station to figure out the problem. Up in the stratosphere, Butler and the station’s director Alexandra Maria Lara discover intentional interference with the system while, down below, Burgess and his Secret Service girlfirend (Abbie Cornish) start sniffing out political corruption and conspiracy. You should be able to suspend your disbelief and allow this to be fun, junky science-fiction, but director Dean Devlin, formerly co-writer on similar films by Roland Emmerich, seems to think he is making The Right Stuffand not When Worlds Collide, and the bad performances by normally better actors give ample evidence of this. A lot of details don’t make sense within the film’s own world, while more than a few visual effects, particularly those involving giant cities being devastated by the extreme weather conditions that result from the malfunctioning satellites, don’t look all that great.
